CHARLIE H. LON G, OF LOUISVILLE, KENTUCKY.

EMERGENCY FUSIBLE CUT-OUT FOR ELECTRIC CIRCUITS.

SPECIFICATION forming part of Letters Patent No. 613,286, dated November1, 1898.

Application filed July 10, 1897. Serial No. 644,099- (No model.)

To all whom it may concern.-

Be it known that I, CHARLIE H. LONG, of Louisville, in the county ofJefferson and State of Kentucky,have invented certain new and usefulImprovements in Emergency Conduotors or Electric Switches; and Idohereby declare the following to be a full, clear, and exact descriptionof the invention,such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in electric switches speciallydesigned for electric-light circuits.

It has for its object to serve as a temporary supply in an emergencyuntil the defect has been permanently remedied, as in the event of theblowing out or fusing of a fuse or fusible wire, arising, as is liable,from certain contingencies with which electricians are familiar.

The invention is adapted for all straightaway and branch blocks.

It consists of the'detailed construction and combination of partssubstantially as hereinafter more fully disclosed, and specificallypointed out in the claims.

In the accompanying drawings, Figure l is a plan viewof my improvedelectric switch, and Fig. 2 is a view showing the switch in side viewand the closure therefor in section.

1 is a base, of non-conducting material, of a switch for anelectric-light circuit.

4 4 are the ordinary fusible wires suitably connected to binding-postsand screws, in turn connected to opposed wire plates 2 3, to which areattached the line wires 10 10 through additional binding-posts andscrews in the usual way, as shown. Opposite binding-posts, with whichone end of each of said fusible wires is connected, are provided withlateral sockets or contacts 8 8.

5 is a strip of conducting material suitably secured to the base 1 andconnected at one end to a lateral arm or extension 2 of one of theprimary wire plates 2 by a fusible wire or link 6, as shown, theopposite end of said strip having pivoted or jointed to ita'laterally-movable lever or switch proper, '7, having asuitably-insulated knot or handle 9 for its convenient manipulation ormovement into and out of engagement with one of the contacts or sockets8.

It is apparent that in event of the blowing or fusing of a wire 4 theswitch can readily be brought into requisition by moving the lever 7 bymeans of the handle 9 into engagement with the opposite socket 8, whereit re mains until the defective wire 4 is remedied, after which it iswithdrawn ready for use in event of another such occurrence. It willalso be seen that this switch, having a fusible link or wire, providesagainst the fusing or blowing of the circuit-wire elsewhere while thedefect arising from the fusing of the wire 4 is being remedied.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In an electric switch, the combination, with the opposed wire plates,spanned by the fusible wires, and opposite ones of said plates havingsockets or contacts, of the laterallymovable switch adapted to engageone of said sockets or contacts and having the fusiblewire connectionwith one of the opposite end plates, substantially as set forth.

2. In an electric switch, the combination, with the opposed wire plates,spanned by the fusible wires, and opposite ones of said plates havingsockets or contacts, of the laterallymovable switch comprising a fusiblemember or link connected to one of said plates by a lateral arm of saidplate, an intermediary member attached to the base, and a third memberconnected to said intermediary member and having an insulated handle orknob,

substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscrib-
